Organic fertilizer comes from plants, animals and mined minerals. Any combination of organic fertilizer will feed soil organisms who produce plant food in a plant available form. Use powdered, pelleted and tablet fertilizer for soil application. Use organic liquid fertilizer or water soluble fertilizers via irrigation or foliar sprays.
How To Get Started The best way to evaluate your own situation is to start with a soil test.
Note to Certified Organic Farmers: While we do our best to stay current with product OMRI listings, be sure to check with your certifying organization for a current list of approved (or banned) products.
